Research Interests (Wolf Lab - RNA sequence-structure phylogenetics)
Abstract: Our research in evolutionary biology and in the systematics of animals and plants focuses on the meeting points of phylogenetics and bioinformatics. Further keywords are molecular systematics, biodiversity, morphology, and taxonomy, as well as biophilosophy (species concepts) and science education. Focusing on alignments and rRNA secondary structures, in particular of the 18S and the internal transcribed spacer 2 (ITS2), as well as on co-developing computer tools inferring RNA sequence-structure phylogenies, we are mainly interested in the phylogenetic relationships and the evolution of protists (protozoa and algae - in particular of alveolates, Euglenozoa, green algae, and stramenopiles), and of invertebrate Metazoa. However, we are working on phylogenetic relationships throughout the tree of life, i.e., on the phylogeny and the evolution of prokaryotes, protists, and Metazoa, as well as on the phylogeny and the evolution of Fungi and 'higher' plants, always connecting organismal- with molecular biology, as well as lab- and field work with computational biology. Our main achievement is the development of the ITS2 database and related software (e.g. 4SALE and ProfDistS). In the context of our phylogenetic RNA sequence-structure analyses, our tools (for alignment and tree reconstruction) are able to automatically process RNA sequences and their individual secondary structures simultaneously.
